7、use the red plugs for Right channel jacks. 3. A record player with MM cartridge must be connected to the Phono Input jacks and a separate ground wire to the ground terminal screw above. Wired Remote Control To control your amplifier with an external infrared remote sensor, connect the wire from the

8、remote sensor to the REMOTE IN jack on the back panel. Or, if another stereo component has a built- in infrared remote sensor and a Remote Output jack, it may be possible to connect this jack to the REMOTE IN jack of your amplifier. All Harman Kardon products with Remote In and Remote Out jacks are

9、compatible with one another, except for the Citation 22, 24 and 25. Other manufacturers remote sensors and components may not be compatible, but it will not hurt to experiment. A second wire may be used to connect your amplifiers REMOTE OUT jack to the Remote Input of another stereo component. Conti

10、nue this process to include additional components (if compatible). Connecting Speakers 1. For best performance, use high quality speaker cables. However, ordinary copper wire can be used if the gauge meets the following requirements: Wire Min. Length Diameter Up to 2.5 meter 1 mm Up to 4 meter 1.25

11、mm Up to 6 meter 1.6 mm Above 6 meter 2- 2.5 mm 2. Avoid rolling excess wire with or near signal interconnects. External Power Amplifiers For applications where higher power is desired, connect the Pre- Out Jacks to the Main In Jacks of an external power amplifier. The level of the output can be adj

12、usted between - 3 and +3 dB with an internal button. To adjust the level, gently insert a small screwdriver into the button and turn clockwise to increase or counter- clockwise to decrease the output level. IMPORTANT: When connecting two pairs of speakers, determine the impedance of each pair by loo

13、king on the back of the speakers, in your owners manual, or by contacting your dealer or manufacturer. You can listen to two pairs of speakers at the same time ONLY if the impedance of EACH speaker is NOT LESS THAN 8 Ohms. WARNING: Do not play sets of speakers simultaneously except as recommended ab

14、ove. Amplifier may overheat. AC Power Plug the cord into a 230 VAC wall socket. Power indicator will light up to indicate power ON. To completely disconnect the power input, the main plug must be disconnected from the mains. 2 RadioFans.CN Controls and Functions Speaker 1Speaker 2Source DirectModeSo

20、 control the amplifier and compatible Tuners, CD Players and CD Recorders. The remote In jack of units without an integrated IR receiver must be connected to the amplifiers remote control output jack so that the system remote control can operate them. The Function Table below will show all functions

21、 of the HK 980 and external devices that can be controlled by the HK 980 remote. Remote button functions Important Notes: To remote control a tuner, CD Recorder or CD Player, the appropriate input (”TUNER”, ”CDR” or ”CD”) must have been selected with the source buttons of the remote control (selecti

22、ng on the front panel is not sufficient). Note that DVD players or tape decks cannot be controlled by the remote. To control a compatible CD Recorder ”CDR” must be selected as input and the drive to be controlled (CDP or CDR) must be selected appropriately with the ”CDP SELECT” or ”CDR SELECT” butto

23、ns. Operating Conditions The control unit operates effectively within a distance of 7 meters and an angle of 30 from the amplifier. Using the control near fluorescent lights may shorten this range, as will any dust or dirt that accumulates on the front of the remote control or the remote sensor area

24、 of the amplifier. Also avoid blocking the line of sight between amplifier and remote. The control unit is powered by two AA batteries, included with your amplifier. When you replace weak batteries, replace both at the same time. When the remote is to be unused for an extended period, remove the bat

34、it would offer full perfor- mance in surface mount packaging. GENERAL DESCRIPTION The OP275 is the first amplifier to feature the Butler Amplifier front-end. This new front-end design combines both bipolar and JFET transistors to attain amplifiers with the accuracy and low noise performance of bipol

35、ar transistors, and the speed and sound quality of JFETs. Total Harmonic Distortion plus Noise equals that of previous audio amplifiers, but at much lower sup- ply currents. A very low l/f corner of below 6 Hz maintains a flat noise density response. Whether noise is measured at either 30 Hz or 1 kH

36、z, it is only 6 nV/Hz. The JFET portion of the input stage gives the OP275 its high slew rates to keep distortion low, even when large output swings are required, and the 22 V/s slew rate of the OP275 is the fastest of any standard audio amplifier. Best of all, this low noise and high speed are acco

37、mplished using less than 5 mA of supply current, lower than any standard audio amplifier. *Protected by U.S. Patent No. 5,101,126. Analog Devices, Inc., 1995 One Technology Way, P.O.
